Silphium was previously used exclusively as an energy crop in bioenergy production. Now, cascading use means that the fibers of the silphium plant can be used to produce sustainable paper and packaging products.

Versatility has a name: Silphium

Silphium has been cultivated in Germany for a number of years now, so far as an energy crop used to produce power, gas and heat. The plant is known for its wide range of benefits:

Energy Crop
used to generate biogas

Perennial culture
that can be used for at least ten years

Protection against flooding and erosion 
thanks to consant soil cover

Humus accumulation and carbon sequestration
in the ground

Long flowering period
and habitat for insects

Alternative fibers
as a raw material for paper production

Promoting indigenous ecosystems
and biodiversity

Good nutrient efficiency 
and less use of pesticides

Wherever silphium blossoms, so too does opportunity

Originally from North America, silphium is now cultivated on some 10,500 hectares (2022) of land in Germany. The energy crop is growing in popularity in other European countries, too.
